Unix system procedure manual/log

(I don’t know if the subject is appropriate to this question 🙂

Can anyone of you ol’ seasoned sysadmins point me to resources on how to develop a manual to document standards, procedures and other useful info to manage Unix systems in a multi-administrator environment.

IMHO, it should feature things like usernames & passwords rules, printer & storage management, backup & security policy, etc… Also, a problem/solution log would be nice.

Am I dreaming or there actually are people doing it, and how?! A good template would help a lot…

Thanks for any useful input!
